recycling water for a better
Water is a scarce resource throughout the world, yet no other natural resource is used more
every single day in every household on the planet. However, as natural water reservoirs and
ground water levels are becoming depleted, the scarcity of water is becoming a dangerous reality
in many countries. Thus, it is only natural that we attempt conservation of water in every possible
Water is not limited to household applications only. Industries need large amounts of water for
manufacturing and production. Because of this, water used and eventually disposed of by
industries becomes unfit for human consumption because it is filled with toxic chemicals, toxic
waste, hazardous gases, and other impurities. The resulting water pollution affects both the water
source and soil when this water is dumped into natural water sources. It also causes soil pollution
that can render soil barren, less fertile, or affect the harvest and growth cycles of consumable
plants and fruit trees.
Eventually, technology and science has produced ways to treat "dirty" water before it leaves a
factory. This treated water is then purified before being released back into natural water sources.
This process is usually called "water filtration treatment."
Effluent Treatment or Water filtration treatment is usually in three major steps:
Primary: Dirty water passes through a wire mesh or wire cloth. Mechanical separators remove
heavy or solid impurities like biological additives and insects. This is a common process even in
households, aside from industries.
Secondary: Effluent water is further filtered through ( visit here ) Aerators. Oxygen is injected into
the effluent water to restore the basic chemical structure of water molecules; oxygen also acts to
remove any further impurities in the water. In some secondary phases, chlorine is added in a
process called chlorination. This is done if the level of chemical impurities in effluent water is quite
high. In a few industries, should the water reach only up to this stage and chlorination still leaves
the water in a high level of impurity, the water is recycled only within the plant to be used for nonconsumption functions like water heating or machine cooling.
The semi-purified water is then made to enter this tertiary phase. This phase is not required in
most cases, however is implemented in specific industrial applications where the impurities like
chemicals, paints, oils, natural gases, etc. are mixed with water to an extend where it becomes
difficult to separate them out by primary and secondary means. In this phase, trickling filters in the
form of organic matter is added to purify the water. Also, rotating biological contractors are added
to purify the biological impurities mixed in water. The quantum of chemicals added is varied
depending upon the composition of water and expected level of filtration.
Effluent Treatment has been proven to be 99.9% effective in purifying water, making it a scientific
success for industrial water treatment. Water filtered in this way even becomes good for human

consumption again. However, the problem of Effluent Treatment is not in the treatment but in the
actual application of the process by industries.
Effluent treatment ( visit here ) is a subject of great environmental repercussion. Industries ought
to take greater responsibility towards the larger ecosystem. Considering the level of
environmental hazards impure water can potentially cause to generations, Effluent Treatment
becomes a matter of state interference. Governmental bodies are more active and constant
checks are conducted on the quality of effluents released by manufacturing units in open waters.
However, much needs and leaves to be done to create a global awareness about the need for
effluent treatment across industry circles.
